METHOD OF DIRECT GRASS SEEDING AND SEEDING MACHINE USED FOR PURPOSE Russian patent published in 2008 - IPC A01B79/02 A01B49/06 

FIELD: agriculture.

SUBSTANCE: suggested process consists of the following activities: cutting out a sod layer slice within the tillage area, its reversal and removal outside the above area with the slice being divided in two equal parts to be finally relocated (unloosened) to the uncultivated spacings stretching along the tillage area border zones, sowing groove formation, dropping seeds into the groove, seed embedment and groove compaction. Sod layer slices are additionally cut out along the both sides of the tillage area at an averaged angle of the slope of repose with the cross section trapezoidal-shaped, larger base upwards, and the sowing groove in the middle. The sowing groove formation and seed dropping are done by way of cutting the sod layer axially thus forming a groove (depth - h_1, density of soil - γ₁)._{Then (after removal of the sod slices outside the tillage area) the groove is additionally cultivated for the depth to be h2 and density of soil - γ2. After that the soil loosened is shovelled into the groove prepared and a new groove is formed in the loose soil combined with dropping of seeds at depth h3. Then the seeds are covered with soil which becomes compacted for the depth of the groove to be h4, soil density - γ4 and seed embedment depth -h3. One shall control the groove depth and soil density parameters so that h1<h2>h3 and γ1>γ2>γ3<γ4. The seeding machine consists of a frame, track rollers, seeding depth mechanism, seed dropping device, colters, bilateral breast hoes, slit cutting knives, suffolk openers, covering knives and spring-mounted support-and-compaction rollers. The seeding machine is equipped with a device intended for deepening the seeding groove formed by the slit cutting knife and a leveller placed immediately behind it. Each colter mounted in front of a breast hoe forms a single unit together with the slit-cutting knife it is equipped with. The breast hoe is additionally equipped with slitting knives attached at its sides and positioned angularly to the hoe horizontal plane. The technology suggested helps to minimise energy consumption of the grass direct seeding process, improve the quality of the seeding groove preparation, enhance uniformity of the seeds embedment depth and optimise establishment of the grass seeds sown.}

EFFECT: minimise energy consumption of the grass direct seeding process combined with quality optimisation.
